这是一段别人的code,有几个问题想请教诸位
- proc report data=AE_tab nowindows split='|' headline spacing=2 headskip missing;<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
- column pag ord AEDECOD _2 _1 _0;
- define pag / noprint order order=data;
- define ord / noprint order order=data;
- define AEDECOD / flow "System Organ Class - Preferred Term" left width=35;
- define _2 / flow " Zemairal|__" "(N=&arm2, SY=&sy2)|n (%)|Events (IR, 95% CI)" width=30;
- define _1 / flow " Placebo|__" "(N=&arm1, SY=&sy1)|n (%)|Events (IR, 95% CI)" width=30;
- define _0 / flow " Total|__" "(N=&tot, SY=&sytot)|n (%)|Events (IR, 95% CI)" width=30;
- title1 j=c "Table 14.3.1-2.5";
- title2 j=c "Summary of adverse events leading to death during the study with exposure adjusted incidence rates (frequencies)";
- title3 j=c "(Safety population)";
- title4 j=c "Page xxxx of yyyy";
- title5 j=c "&fline.";
2. define pag / noprint order order=data;
define ord / noprint order order=data;
这里为什么要加order=data
3. spacing=2 是什么意思
4 平时总是搞混order group display ,有什么好办法区别他们么
